I do think that it is not supposed to happen. But before digging a little deeper to try to find out where the error comes from, I wanted to be sure. Any clues?

I am running a clean install of Zope-2.7.2 and Python2.3.

Hi Damien, I've reproduced your problem. Changing the owner of /folder (and there by all the others) to viewer lets viewer access title_or_id. title_or_id is published with __allow_access_to_unprotected_subobjects__ in SimpleItem:Item. It seems like the owner of an object with "unprotected subobjects" needs to have View permission for the "unprotected subobjects" to be accessable to the world. Methods declared __allow_access_to_unprotected_subobjects__ is very similare to being declared public I guess? Cheers, Johan Carlsson
